Could you try logging out -and in via the CC app (this is important) and not via the browser and restart Lr Desktop afterwards? See instructions here: Sign in, Sign out | Creative Cloud desktop app
If that won't help please try a reboot of your machine after the logout.
Let us know the outcome
I did sign out and back in through the cc app. That did not work. I then
uninstalled and reinstalled lightroom 6 and then signed out and in through
the cc app and still will not load.

I also signed out of cc app then rebooted pc. I then signed back in to cc
app but it still will not load. I get the spinning circle for about 5 or 6
seconds then nothing.
